never really knew much about Arduino...but I've got hundreds of old AOL and other free CD discs handouts that I saved from back in the day, cause I always thought they would be neat to make something out of(I was thinking a snake scale like shower curtain or something) and saw this video one day https://www.youtube.com/watch?v=yscv1555QpM < cation : don't start jamming on that music too hard :
...so then I had to figure out what Arduino was

you're not by any chance making a "light up to music CD shower curtain" are you?

This is my build: http://elmoto.net/showthread.php?t=4354
I'm using Arduino Uno to design a dashboard/control interface for my EMC.
So far, I have it successfully turning on the bike's power without a key, just using my Android cell phone. My phone will display the coolant temperatures and the Battery temperatures. The app I'm using is called Virtuino. The temperature monitors also save max and min temperatures received, which is a nice feature to review after the ride. I need to learn how to build an interface to monitor individual cell voltages, but for now, I'll just use Cell Logs.
